Double-motor power-driven system of electric automobile

Abstract

The invention discloses a double-motor power-driven system of an electronic automobile. The double-motor power-driven system of the electronic automobile comprises a first driving motor, a first storage battery group which corresponds to the first driving motor, a second driving motor, a second storage battery group which corresponds to the second driving motor and two centrifugal one-way automatic clutches. The first driving motor and the second driving motor which are conjoined are arranged in the power-driven system in a parallel mode, the two centrifugal one-way automatic clutches which are arranged in a parallel mode are respectively connected with power output ends of the first driving motor and the second driving motor, the two centrifugal one-way automatic clutches are connected with an output end of an electromechanical coupling gearbox through a spline shaft, the output end of the electromechanical coupling gearbox is connected with a transmission shaft of a vehicle. The double-motor power-driven system of the electronic automobile has the advantages of solving the problem that the automobile is underpowered under the conditions of starting, overtaking, uphill, passing ditches and the like, and switching the underpowered motor in a double-motor group when the vehicle dynamically moves forward.

Description

technical field [0001] The invention relates to a drive arrangement structure of an electric vehicle, in particular to a dual-motor power drive system for an electric vehicle. Background technique [0002] Today, due to the depletion of petroleum resources and the severe environmental pollution caused by vehicle exhaust emissions, the development and development of new energy vehicles has been promoted to a major national policy and a long-term strategic goal. Develop new energy vehicles to reduce the consumption of petroleum resources and protect the living environment on which human beings depend. There is no delay. [0003] At present, the common problems of pure electric vehicles at home and abroad are: lack of power, can not run fast and not far, the vehicle cannot charge and supplement energy by itself during dynamic driving, and therefore pure electric vehicles are forced to stop due to insufficient power supply , At the same time, there is an urgent need for fixed ...

Problems solved by technology

[0003] At present, the common problems of pure electric vehicles at home and abroad are: lack of power, cannot run fast and not far, vehicles cannot charge and supplement energy by themselves during dynamic driving, and thus cause pure electric vehicles to be forced to stop due to insufficient power supply , At the same time, there is an urgent need for fixed charging and swapping stations on the ground to complete the cumbersome procedures of charging and swapping, etc.

In addition, since pure electric vehicles usually need to rely on ground fixed charging stations to supplement power energy, there are great limitations in the use of pure electric vehicles, which directly affects the widespread popularity of pure electric vehicles and the favor of users
